Current APHIS Veterinary Services (VS) disease eradication programs include

cooperative State-Federal efforts directed at cattle and swine brucellosis, bovine and

cervid tuberculosis, and pseudorabies in swine. The following table shows the status

of States in these programs.

About Our Work

Disease control and eradication measures include quarantines to stop the

movement of possibly infected or exposed animals, testing and examination to

detect infection, destruction of infected (sometimes exposed) animals to prevent

further disease spread, treatment to eliminate parasites, vaccination in some cases,

and cleaning and disinfection of contaminated premises.
APHIS animal health programs are carried out by a field force of about 250

veterinarians and 360 lay inspectors working out of area offices (usually located in

State capital cities). Laboratory support for these programs is supplied by APHIS'

National Veterinary Services Laboratories (NVSL) at Ames, IA, and Plum Island, NY,

which are centers of excellence in the diagnostic sciences and an integral part of

APHIS' animal health programs.

Under the Virus-Serum-Toxin Act of 1913, APHIS enforces regulations to assure that

animal vaccines and other veterinary biologics are safe, pure, potent, and effective.

Veterinary biologics are products designed to diagnose, prevent, or treat animal

diseases. They are used to protect or diagnose disease in a variety of domestic

animals, including farm animals, household pets, poultry, fish, and fur bearers.

In contrast to animal medicines, drugs, or chemicals—all of which are regulated by

the U.S. Food and Drug Administration—veterinary biologics are derivatives of living

organisms. Unlike some pharmaceutical products, most biologics leave no chemical

residues in animals. Furthermore, most disease organisms do not develop resistance

to the immune response produced by a veterinary biologic.

Veterinarians and other professionals in APHIS' Center for Veterinary Biologics

regulate and license all veterinary biologics as well as the facilities where they are

produced. They also inspect and monitor the production of veterinary biologics,

including both genetically engineered products and products produced by

conventional means. Necessary tests of veterinary biologics are conducted at the

NVSL.

APHIS also regulates the licensing and production of genetically engineered vaccines

and other veterinary biologics. These products range from diagnostic kits for feline

leukemia virus to genetically engineered vaccines to prevent pseudorabies, a

serious disease affecting swine. With the pseudorabies vaccines, test kits have been

developed to distinguish between infected animals and those vaccinated with

genetically engineered vaccines.
